Abstract

PURPOSE:To enhance the rigidity of a unit air filter, by constituting a frame body of both side wall parts and frame members comprising top wall parts having recessed groove parts connecting both side wall parts and connecting corner parts by connection jigs. CONSTITUTION:In an air filter, both side wall parts 111, 111 are provided in opposed relationship and one ends thereof are connected by top wall parts 112 to form a C-shaped cross-sectional shape and recessed groove parts 113 are formed to the outsides of said top wall parts 112. The connection parts of each frame member are formed by cutting both end parts thereof at 45 deg. and fixing a connection jig 2 having a thickness and width capable of being engaged with an engaging mount hole part 114 and formed into an L-shape to each top wall part 111 by clamp members 3 such as rivets. Because a frame body 1 is formed by connecting and fixing the corner parts thereof by the connection jigs 2, the corner parts become strong and the frame of a filter unit generates no deformation due to bending or the like and the mounting of the filter unit to machinery can be easily and surely performed.

アフィルタを創案することを目的とする。(Problems to be Solved by the Invention) In the conventional air filter having the above-mentioned structure, during use, the caulked portion by the rivet becomes slack, and then each frame member fitted into it becomes loose at the four corners. With the rivet as a fulcrum, it can be easily deformed and twisted into a rhombus or parallelogram shape, and the side wall and top wall of the frame member can be easily deformed due to its shape. It has become,
Workability is poor when fitting and installing each device, and
The periodic removal and installation of the filter element for cleaning can be difficult and require a lot of effort, and when it is installed in the equipment, vibrations caused by the operation of the machine body can cause buzzing noises. In extreme cases, cracks may occur around the rivet holes and slits, which may lead to unusable damage. Therefore, the rigidity of the frame members and frame body should be increased to ensure ease of handling and safety. The purpose is to create a highly efficient air filter.
